SEL-321/321-1 Instruction Manual
Category Setting Comment
TIMEOUT 0 Time relay waits after last command received before relay
reverts to Access Level 0 and aborts any command in
process (0.00-30.0 minutes). If set to 0, port never
times out.
AUTO Y Y = Port set to AUTO.
RTS_CTS N N = RS232 request to send - clear to send handshake
protocol is OFF (see Communications Protocol earlier
in this section).
Y = Protocol on. Should be set to Y for use with modem.
MBT = MBT9600 modem used with PROTOCOL = MB.
FAST_OP
(SEL-321-1 Relay
only)
N N = Disable fast operate command processing.
Y = Enable fast operate command processing. (See Fast
Operate Command Processing Application Guide).
STATUS
STATUS allows inspection of self-test status. The relay automatically executes the STATUS
command whenever the self-test software enters a warning or failure state. If this occurs, the
relay transmits a STATUS report from the port(s) designated automatic (see SET command,
AUTO setting). Type STATUS 4 to view the status information four times.
The STATUS report format appears below:
=>STATUS <ENTER>
STATUS <ENTER>STATUS <ENTER>
STATUS <ENTER>
